Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.

19/12/2019 · The aggregate crushing value test indies the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength low ...

Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is suggested by AASHTO T 96 or ASTM C 131: Resistance to Degradation of SmallSize Coarse Aggregate by Abrasion and Impact in Los Angeles Machine. The aggregates are used for the surface course of the highway ...

Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surfacedry sample

May 07, 2013 · The ratio of the weight of fines formed to the total sample weight in each test is to be expressed as a percentage, to the first decimal place. Aggregate impact Value = (W B / W A) × 100. Precautions. Use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes goggles at the time of testing.
